Title: Manufacture of insulated gate type semiconductor device
Inventor: YAMAZAKI SHIYUNPEI
IPC: G02F1/1368
Filed: 1983-10-03
Abstract: PURPOSE:To operate the titled semiconductor device at higher frequency by forming a conductor or a semiconductor shaping a gate electrode while being adjoined to an insulator so that the upper end section of the gate electrode is not left on a third semiconductor. CONSTITUTION:A first conductive film 2 is formed on an insulating substrate as a lower side electrode and a lead, and etched selectively (1). A P or N type conduction type first nosingular crystal semiconductor 3 (S1), a second insulator or semi-insulator 4 (S2) and a third semiconductor 5 (S3) having the same conduction type as the first semiconductor are laminated on the upper surface of the conductive film, and a laminate (S) is formed. When a resist 18 is shaped on the upper surface and anisotropic etching from the vertical direction is executed, these conductors can also be left to sections except a region, in which there is the mask 18, as shown in broken lines 38, 38'. Consequently, gate electrodes can be formed selectively only to the side periphery of the laminate. There is not gate electrode in the upper section of the third semiconductor, and unnecessary sections in the gate electrodes 20, 20' formed to the whole outer circumferential sections of the laminate are removed through a photoetching method of 5.

Title: Conveyer
Inventor: MUNENAKA KATSUMI
IPC: G03G15/00
Filed: 1986-08-06
Abstract: PURPOSE:To surely obtain electrical conduction of a guide member further to swivel the guide member accurately further stably, by forming one part of a supporting member, which comes into contact with a metallic part of the guide member, from metal. CONSTITUTION:A guide member 2 is rotatably provided for a pin 3 with a supporting point A serving as the center. The pin 3 is obtained by injection molding by integrally forming a pin main unit 3a, consisting of plastic material, with a cylindrical pipe 3b made of brass. Conduction between the pin main unit 3a and the cylindrical pipe 3b is ensured because they are integrally molded. A device, stopping the pin main unit 3a by a machine screw 11 to a device main unit side plate 7, ensures conduction between these pin main unit 3a and device main unit side plate 7. While conduction between the cylindrical pipe 3b and a bottom side guide plate 2b is ensured because they are formed by fellow metals. Accordingly, a necessary electric characteristic can be realized for the guide member 2 because the conduction is surely obtained between the device main unit side plate 7 and the guide member 2 through the pin 3.

Abstract: PURPOSE:To achieve the formation of a narrower electrode, by a method wherein, a protruded part whose cross section is shaped like an inverted trapezoid is formed and an insulating film is formed by referring to the interval of the length of the base of this protruded part, and a groove is formed by making use of this insulating film as a mask. CONSTITUTION:A buffer layer 2, an N-type active layer 3 and an N<+> type conductive layer 4 are successively grown on the surface of a semiinsulating GaAs substrate 1. A photoresist layer 5 is coated on the whole surface of the conductive layer 4 so that a pattern for the formation of a gate electrode can be formed. By making use of this photoresist layer 5 as a mask, this assembly is processed by means of anisotropic etching, and a protruded part 4 whose cross section is shaped like an inverted trapezoid is formed. Then, an SiNx film 6 is formed on the substrate. The SiNx film 6 is deposited up to the skirt part of a protruded part 4' due to a growing gas creeping into the skirt part during this process. Then, the resist layer 5 existing on the protruded part 4' is removed and at the same time the SiNx film existing on this resist layer 5 is removed. In addition, the protruded part 4' can be removed after the etching process by making use of the SiNx film 6 as a mask, and then a recess 7 whose cross section is shaped like a trapezoid can be formed by means of anisotropic etching. The recess is finally formed after it is excavated down to the active layer 3.

Filed: 1981-11-20
Abstract: PURPOSE:To normally and reliably detect a breaking condition of a paper, by a method wherein widths, at a plurality of spots, crossing a conveying direction of a paper to be conveyed at right angles, are measured, and the results are respectively compared with a reference value. CONSTITUTION:A paper P, conveyed by a line sensor 13, is scanned in a direction (b), crossing a conveying direction (a) thereof at right angles, a given number of times (n times). Widths W1-Wn, at a plurality of spots, meeting the conveying direction (a) of the paper P at right angles, are measured, and measurements Wi(i=1-n) are compared, in order, with a reference value Wx. In case a given number of the values Wi (a reference value Wy) being smaller than the value Wx is obtained in sequence, it decides that a break occurs in the paper P. This permits a breaking condition to be normally and reliably detected even if the paper P has a broken corner, fluctuation in thickness, and contamination.
